DC vacuum pump DVH145-X1 12V, 3 l/min - Nitto Kohki 193104152

Where neither mains power nor a central vacuum supply is available, this series generates -400 mbar at 3 or 7 l/min free air displacement from 12 V or 24 V DC. All models run in continuous duty and use the same 76 x 70 mm mounting pattern.

• Mains-independent operation from a battery or on-board system at 12 V or 24 V DC
• Predictable current draw between 0.34 and 0.86 A mean value, which allows clean battery and fuse sizing
• The same vacuum level of -400 mbar across the whole series, so selection comes down to the required displacement of 3 or 7 l/min
• Long maintenance intervals thanks to the stated service life of 10,000 operating hours on every model
• Continuous duty without forced pauses, which suits permanent holding and pick-up functions
• Consistent installation with 76 x 70 mm mounting dimensions, 0.91 kg weight and a 6 mm outside diameter hose barb

Applications

• Vacuum grippers in battery powered handling units
• Picking up and holding parts in mobile fixtures
• Sampling and extraction in portable measuring instruments
• Vacuum functions in vehicle bodies and special purpose vehicles
• Holding and clamping stations on off-grid test set-ups

Operating principle

A coil-driven piston draws the air in and pushes it out through the hose barb at the outlet. The coil winding is rated to insulation class A.

Standards and compliance

Coil insulation is classified as class A or equivalent to JETL.
